Hi,
Wondering if anyone has insight into Code requirements for
securing/supporting PV wire behind the modules?
I am aware that USE-2 sends you to Section 334.30 requirements for Type NM
(12" from box, every 4.5 ').
However, I think this is totally bogus, for 2 reasons.
1) Section 338.10(B)(4)(b)
Hi Wrenches,
Does anyone know of a product or method to hide the white back sheets of
modules mounted on a pole mount? I envision some type of taunt fabric
almost like a shade cloth that will darken it up.
Thanks

Mac,
Yes, we used a silicon based paint and covered the UL label with a
detachable sticker. We got the manufacturer to approve it. The silicon
paint did not appear to interfere with the cooling of the module in our
very limited testing. Screening with solarscrim would probably also work
and accomp
Hi Rebekah
Many, not all, OutBack Distributors offer design and tech support as well to
dealer/installers. In most cases they will be able to answer questions on a
larger range of products as well.

Friends:
I inspected a mobile system recently that consisted of a set of vented
lead-acid batteries directly below a rack of Outback FX inverters and
Flexware cabinets. The batteries were not covered. They did have a dual
set of tubes connecting the caps. When I asked about the possible safety

Are you using this method on roof top systems that are parallel to the roof

I don't want to bring up the question of what cost this adds to the job

Thank you for responding Sandra. I appreciate you offering your direct number.

Kinetic rails offer the same channels (similar design), and we always lay
the wires in the channels when possible, which still requires either a
nylon or stainless steel cable tie to hold the wires in.
Kinetic recently revised their rails design which has an additional PV wire

Ben:
Yes, we do use this technique on roof mount systems as well. This is true
for micro-inverters and string inverters alike. The PVC holds trunk cables
and DC cables alike.
The attention we pay to detail does add to the cost of our jobs. The
development time adds to the production costs.
Dana,
SESA (Solar Energy Society of Alberta) has been providing a great service
to anyone interested in Solar Energy for many years. One project touches
on what a PV system will produce at various angles here in Edmonton and the
result of snow removal, or not, in particular.
I've been meaning to
Now that I am teaching electrical/solar more than installing electrical/solar I
am designing labs and systems for education. As part of my classes I spend

Todd,
I've seen that photo of yours before. Yeah, that is really something!!!
A few questions
Have you seen it happen on systems or sites other than the one in the photo?
What brand of modules? Were they covered under warranty? If not, Why not?
So was this a result of some snow accumulation
benn,
yes, this has happened to me on two sites (until i learned this type of mount does not work). one had mitsubishi modules and another evergreen modules. other colleagues here have had these painful "learning opportunities" too. both of these jobs were for customers who insisted on roof, rath
